So it’s not just about emissions: pollution matters too. The authors quote studies that show clean energy portfolios (CEPs) not only reduce energy costs, but can save billions of dollars in community … [Read more...]

If they don’t reach far, local coal plants must ramp down - but only if they’ve been retrofitted to be able to do so.
